Introduction: Soda Fountain 2
My soda fountain does not operate an C02 simply uses a small electric pump.This is my first instuctable and its not very good(I had to take it apart and redo it for this) I hope to have a better version of it soon.
Step 1: What You Need
- A plastic base of some sort
- A small elctric pump
- 6v power supply (I got mine from an old CD player)
- 5ft of tubing (an air hose for a fish tank works the best)
- 2 LEDs and a 100ohm resistor (this is just to make it look cool.It is obtional)
- A toggle switch
- Wire (I dont know what guage.Just go for pretty thin)
- A fish tank tube connector and half a foot of tubing (optional)
- A 2 litre
- A soldering iron
- Wire strippers and cutters
- electrical tape
- A hot glue gun
Step 2: Getting Started
(sorry I did this kindove backwards.You might want to drill all the holes THEN attatach all of the components)
First of all you have to find the input and output for power and drink of your choice on the pump. Once you have found it drill a hole in your base and connect the tube from the output into the spout (USE LOTS OF HOT GLUE) . Next drill a hole in the back of the base,feed the 5ft tube through and connect the tube to the input of the pump OR if your using a connector, feed a small ( about half a foot) of tube through and connect to the output then on the other end connect the connector.
Step 3: LEDs
Now for the LEDs. For this step I'm expecting you know how to wire LEDs up to a 6v power supply witha 100ohm resistor. Drill 2 holes wearever you want the LEDs to be, then hook up the wires from the LEDs to the switch and the power supply. Now When you turn on the pump the LEDs turn on too.
Step 4: The 2 Litre
First, drill a hole in the cap of the two litre big enough for the hose to fit through. Then Drill a very small hole for air, you need this hole because when the the liquid is pumped out, air needs to get in to replace it.This is bad because after while the pop goes flat. If you have any improvements let me know in the comments.
Step 5: Finsh!
I don't think I forgot anything... If you need more info or you have improvements tell me in the comments. Enjoy!
